HENRY BARTON, OF CHARLESTON, WEST VIRGINIA.

STEAM-BOILER AND FURNACE.

SPECIFICATION forming part of Letters Patent No. 632,624, dated September 5, v1899.

Application filed December 9, 1898. Serial No. 698,747x (No model.)

To all whom it may concern;

Be it known that I, HENRY BARTON, a citizen of the United States, residing at Charleston, in the county of Kanawha and State of .Vest Virginia, have invented certain new and useful Improvements in Steam-Boilers and Furnaces; and I do declare the following to beafull, clear, and exact description of .the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to new and useful improvements in steam-boilers and furnaces, and especially to the provision of an inner and an outer boiler,with an intervening space between the two through which the heat and smoke are allowed to circulate from the furnace to the chimney.

More specifically this invention resides in the provision of an inner circular or cylindrical-shaped boiler, to which a dome may be connected when it is desired to use the device for a steamer, the boiler being designed to contain within the space formed by its inner curved wall a hopper for containing fuel, which is allowed to be fed through an aperture in the boiler to the furnace-grates. Surrounding the inner boiler I provide a second or out-side boiler, which is preferably U- shaped in longitudinal section, which second boiler extends about one end of the circular or cylindrical boiler, suitable return-bends being provided to connect the two boilers,and fiuesformed for causing the heat from the furnace to come in contact with all sides of both boilers.

To these ends and to such others as the invention may pertain the same consists, fur

and water heater, showing a portion of the front wall removed. Fig. 2 is a side elevation with parts broken away to illustrate the smoke passage-way through the flues. Fig. 3 is a rear elevation of the boiler and steamer. Fig. 4 is a horizontal section through the two boilers.

Reference now being had to the details of the drawings by letter, A designates the inner cylindrical-shaped boiler, which is suitably mounted within the walls surrounding the boilers on bearing-bars A, secured to the plate-iron forming the outer boiler B. Vithin the space formed by the cylindrical boiler is placed a hopper O for containing fuel, and directly underneath said hopper is an aperture through the cylindrical boiler directly over the fire-grate D of the furnace, whereby 7. the fuel mayfall thereon from the hopper. Then the two boilers are adjusted in place, the upper portion of the inner boiler will extend, preferably, somewhat higher than the upper portion of the outer boiler. This outer boiler is made U-shaped in longitudinal section, with its bent portion extending about the rear end of the inner cylindrical boiler, as shown, a slight space intervening between the two boilers sufiicientto allow for the cir- 8o culation of the heat and smoke from the furnaoe in its course to the chimney.

The inner and outer boilers are connected by means of return-bends E at theforward ends of the boilers, and a feed-pipe F may be connected with the outer boiler at its curved portion. In order to form fines for the passage of the smoke and heat from the furnace to all sides of both boilers, I provide partitions G, which extend between the outer 0 wall of the outside boiler and the brick wall H,which surrounds the latter. Suitable studbolts K are provided for securing the firefront to the boiler and pipes L for blowing off water when it is desired to clean out said boilers.

\Vhen it is desired to utilize the boilers for the purpose of generating aquantity of steam, I provide a steam-dome M, which is fastened steam-tight to the inner cylindrical-shaped 10o boiler and communication had between the two through an opening in the wall of the inner boiler.

Mounted at the rear end of the inner boiler and designed to close the space between the rear end of said boiler and the curved portion of the outer boiler is a damperR,whereby the course of the smoke and heat may be directed as desired.

From the foregoing, when taken in connection with the drawings, it will be noted that the heat and smoke from the furnace will pass up and about the outside of the inner boiler and through its interior space in which the coal-hopper is contained, and thence pass up and over the upper wall of the outside boiler and down, following the course indicated by arrows in the drawings, passing through the upper flue, thence forward and backward through the second flue, thence to the chimney.

While I have described but one set of fines, it will be noted that each side of the furnace is provided with a similar arrangement of fines, whereby the heat from the furnace will reach all parts of the boilers.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

titions and the front walls of the flue-chambers, smoke-fines over the upper rear portionand about the lower portion of the rear end 40 of the outer boiler, forming a communication between the furnace and the chimney, as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY BARTON.
